SURGICAL PAD Specification of Letters Patent. Patented Feb. 25, 1908.

Application filed March 2. 1907. $erial No. 360.288.

To all whom it may concern:

Be it known that I, JAMEs A. MURRAY, a citizen of the United States,residing at New Haven, county of New Haven, and State of Connecticut,have invented certain new and useful Improvements in Surgical Pads, ofwhich the following is a specification.

My invention relates to certain improvements in pads for use in surgicalandob stetrical ope1ations;

An important feature of the invention consists in so constructing thepad that'when not in use it will assume a perfectly flat form and may beclosely folded or rolled into a compact package convenient to handle andof such size as to occupy but very small space in a bag or instrumentcase.

A second feature of the invention consists in continuing the inflatabletubing, which ordinarily extends around the pad, down- -ward along thesides of the apron or extension thereof, in order to stiffen the sameand increase the thickness at the edge sufficiently to prevent overflpw.

third feature consists in reducing the diameter of the inflatable tubingbeyond the body of the pad proper so that the weight of the apron willbe sufficient to overcome the stiffness imparted to the same by theinflated edging and cause it to bend downward at a proper angle. I

A fourth feature consists in constructing the pad so that it and itsintegral apron extension, edged as above described, have substantiallythe same form on both sides and an effective depth, equal to or greaterthan that of the ordinary non-reversible pad and apron, thus permittingeither side thereof to be used and the pad to be reversed at will,without requiring any preliminary manipulation whatever.

A pad suitable for carrying my invention into effect is illustrated inthe accompanying drawings. I wish it understood, however, thatI do notlimit myself to either the exact form or construction shown, as variouschanges may be made therein without departing from the spirit and scopeof my invention.

In the drawings: Figure 1 is a plan view of the pad before it isinflated. Fig. 2 is an edge view of the same. Fig. 3 is a cross sectiontaken on the line s 8 of Fig. 1. Fig. 4

line 8, s, of Fig. 4, and Fig.

is a plan view of the pad inflated, showing a portion broken out andturned up to present the edge. Fig. 5 is a side view of the padinflated. Fig. 6 is a cross section on the 7 is a similar view showingthe effective depth of the pad when in use.

Referring now to the drawings, 1 represents the body of the pad whichmay be given any shape desired, but is preferably rectangular as shown,and forming a continuation thereof, there is an apron or extension 2,the width of which is gradually reduced to permit the lower end to entera suitable receptacle in the usual manner.

Forming an edging extending from the bottom of the apron along bothsides thereof and upward around the pad, there is an inflatable tube 3.As shown, the size of the tubing is reduced at the point where the apronjoins the pad proper and thus constructed, the weight of material in theapron is sufficient to bend the tubing and maintain the apron at aproper angle.

4 indicates a spring closed valve of well known construction controllingthe admis sion and exhaust opening of the tubing.

The pad may be formed of a single piece of material by being firstproperly blanked to provide portions suitable for forming a flat tubularedging when folded over upon the body portion and secured, or ifpreferred, the tubing may be formed separately and secured as shown inFig. 6 for example. In either case the relative arrangement of the bodyportion of the pad and the tubular edging would be such as to render thepad reversible and equally effective regardless of which side isuppermost.

Referring to Fig. 3, it will be observed that in a collapsed state, thetubing lies sub stantially in the plane of the body portion and wheninflated forms a raised edge upon opposite sides thereof, which servesto yield ingly maintain the body proper elevated or above the plane ofits su port and combines with it to form a reversi le receptacle such asis shown in Fig. 6. The depth of the receptacle thus formed ispractically doubled in use, as the pad yields under theweight of thebody of the patient and assumes the form shown in Fig. 7.

The method of use and the many important advantages of my invention willbe apparent from the foregoing description. 7

Having, therefore, described my invention, I claim:

1. A surgical pad formed of a sheet of material shaped to provide a bodyportion and an apron forming a continuation of the body portion andadapted to extend downwardly at an angle thereto, said sheet having1inflatflible portions extending throughout its engt 2. A surgical padformed of a sheet of material shaped to provide a body portion and anapron forming a continuation of the body portion and adapted to extenddownwardly at an angle thereto, said sheet havinginflatable portionsextending throughout its length and breadth.

3. A surgical pad comprising a body portion provided with an inflatableedging and an apron havin a similar edging of smaller diameter than t atof the body portion and forming a continuation thereof.

4. A surgical pad comprising a body portion and an apron provided withan inflatable edging, the diameter of which is reduced at the pointwhere the apron unites with the body portion of the pad.

5. A surgical pad comprising a body portion, an apron extension movableinto angular relation to the body portion, and an inflatable tubearranged as an edging about the body portion and apron.

6. A surgical pad comprising a body portion, a tubular edging secured tothe body portion and providing a raised support for the same wheninflated, and an apron formed as a continuation of the body portion andhaving the tubing extending along the sides thereof.

7. A surgical pad com rising a body portion, a tube secured to the bodyportion in such relation as to provide a raised edge upon opposite sidesthereof when inflated and an apron formed as a continuation of the andmeans for pneumatically stiffening the apron.

9. A surgical pad comprising a body portion downwardly therefrom andprovided with inflatable portions.

10. A surgical pad comprising a body portion having an apron extensionadapted to extend downwardly therefrom, the thickness of the apron beingincreased at the edge to form a flat tube. a

11. A surgical pad comprising a body portion, an apron forming acontinuation of the body portion and adapted to extend downwardlytherefrom, and a tube secured as an edging to the body ortion and apronand arranged in such re ation as to yieldingly support the body portionin an elevated position when inflated.

12. A surgical pad comprising an inflatable portion, and anon-inflatable portion relatively arranged to provide a flexible bodyand apron extension having a raised edge extending above and below thesame.

13. A surgical pad comprising an inflatable portion and a non-inflatableportion relatively arranged to provide a flexible body and apronextension, the thickness of which at the edge is increased to the sameextent upon opposite sides thereof.

In testimony whereof, I aflix my signature, in the presence of twowitnesses.
